Altruism, an act that bestows a benefit on the recipient while conferring a cost to the actor, is one of the central paradoxes of evolution. In the wild, where only the fittest survive, adopting other animals’ offspring is not really in line with Darwin’s theory of evolution. And yet, amongst bees, dolphins, lions and several primate species, altruism may go as far as adoption. In the case of social insects, parent substitution was a flaw in Darwin’s theory of evolution by natural selection: the biologist noticed that non-reproductive insects who adopted and helped young ones, brought a large portion of genetic baggage from their parents. Darwin had to broaden his theory to the family group. For mammals, including men, what advantage is there in the act of adoption? In the years following the adoption, does the adopted individual contribute to the foster parents’ survival and vice versa? The controversy at the heart of this documentary continues to be debated in today’s scientific world. While raising these different questions, this documentary will study each case separately because each adoption behaviour has evolved independently forming its own pattern, its own benefit and even…its own disadvantages.

Language
An Indonesian legend claims that monkeys can speak but they prefer to stay quiet. Do animals have languages that we don’t understand? Is it just a question of getting the right dictionary or is language the one thing that separates humans from the rest of the animal kingdom? Birds sing, lions roar and chimpanzees chatter but do these noises mean anything? This one-hour documentary takes viewers into the wild to listen to nature’s noisemakers and meet some of the scientists who spend their days trying to have conversations with animals. From parrots to killer whales we find out who is saying what to whom and explore whether there is such a thing as animal language.
